Stop guessing your Amazon, eBay, Shopify & TikTok profit — see it in black and white

Gross revenue is just the top-line sales number—what the customer pays. True net profit subtracts every cost tied to that SKU: product cost, Amazon referral fees ($3.20 on a $20 item), shipping, ad spend, refunds, even currency conversion losses. We’ve seen SKUs where gross revenue looked healthy, but after all fees and refunds, the true net profit was negative 8%. That’s why we built Gomarginify—to show the real money in your pocket, not the fantasy on the dashboard.

Absolutely. Last month SKU B07X showed $1,200 in sales, but after fees and refunds, it lost 12% margin. Gomarginify flagged it on day three with a ‘losing SKU’ alert. We’ve had sellers cut 18% of their catalog after seeing the same diagnostics. The tool doesn’t just report numbers—it tells you which SKUs to pause, reprice, or relist before they drain your cash.

Yes. We connect to 10 marketplaces—Amazon, Shopify, TikTok Shop, Temu, eBay, Etsy, Walmart, AliExpress, Shopee, Lazada—and pull in every fee structure automatically. Temu’s 8% platform fee? We include it. Shopify’s 2.9% + $0.30 per order? Covered. We even handle currency conversion so your profit reports stay accurate whether you’re selling in USD, EUR, or IDR.

We split FBA and FBM costs right down to the SKU level. For FBA, we include the referral fee, fulfillment fee, and storage fees. For FBM, we add the referral fee and your shipping cost. Last quarter, a seller switched fulfillment in March and saw their profit jump 7% overnight—Gomarginify showed them exactly where the savings came from.

We cover both. For KDP authors, we factor in Amazon’s royalty tiers, printing costs, and delivery fees. For seller accounts, we include referral fees, FBA costs, and ad spend. One author told us they were using a KDP calculator that missed 15% of their actual costs—until they ran the same numbers in Gomarginify and realized their true margin was 22% lower than they thought.

Yes. We pull in each marketplace’s fee structure—Temu’s 8% platform fee, Shopee’s 2% transaction fee, eBay’s 12.9% final value fee—and calculate true net profit per SKU. A seller we worked with found that Shopee had a 19% margin on a bestseller, but Temu’s 8% fee made it unprofitable. Gomarginify flagged the shift within a week.

No credit card required. Sign up, connect your marketplaces, and run a full profit analysis for 7 days. You’ll get daily profit reports via email and IM (Slack, Discord, Telegram, WeCom, Lark). After the trial, you can upgrade to a paid plan—no surprises, no hidden fees. We’ve had sellers cancel subscriptions after the trial because they realized they were losing money on SKUs they thought were profitable.

We automatically convert all sales to your base currency (USD, EUR, GBP, etc.) using daily exchange rates. If you sell in EUR but your costs are in USD, we show your true profit in USD so you’re not guessing. A seller in Germany told us they were losing 6% on every EUR sale because they weren’t accounting for conversion losses—Gomarginify fixed that in one click.
